I'm a french student and with three friends we have to realize a project for our exams. We want to make a robot which uses a CMUCAM4 with Arduino. In the CMUCAM4 there is a test mod which track a color. We have found this program (http://www.cmucam.org/docs/cmucam4/arduino_api/_c_m_ucam4_8cpp_source.html), and we don't know if it's the program of the test mod, because we need it. And I found another program and it's the same problem :

void loop(){ while(!cam.getButtonPressed()); // Wait for the user to press the button...

CMUcam4_tracking_data_t data;

cam.trackWindow(RED_THRESHOLD, GREEN_THRESHOLD, BLUE_THRESHOLD);

for(;;) { cam.getTypeTDataPacket(&data); // Get a tracking packet.

// Process the packet data safely here. }

// Do something else here.}
